要显示PXF状态，必须在Greenplum数据库集群中的每个segment主机上显式请求PXF服务实例的状态。

只有`gpadmin`用户可以请求PXF服务的状态。

执行以下步骤，可以以在Greenplum数据库集群中的每个segment主机上请求PXF状态。

1. 登录gpdb集群的master主机

    ``` shell
    $ ssh gpadmin@<gpmaster>
    ```

2. 使用`gpssh`命令和`seghostfile`在每个segment主机上运行`pxf status`命令：

    ```shell
    gpadmin@gpmaster$ gpssh -e -v -f seghostfile "/usr/local/greenplum-db/pxf/bin/pxf status"
    ```
